KIT assembly instructions

All components

Soldering in six steps

1 - bottom pad J1 USB connector
2 - U5 DIL socket
3 - RL1 Relay
4 - P1 P2 P10 P11 JP1 Pin header
5 - S1 Reset button
6 - J2 D-SUB connector

❏ Short JP5 JP6 SMD jumper padds on bottom side

Display

❏ Deploy from the left side Left LCD holder on PCB board

❏ Put LCD

❏ Deploy Right LCD holder on display and deploy to PCB from front side

❏ Display cabe - using only one same side of connectors

❏ Connect display and PCB board - Green collor shows polarity

❏ Insert PCB with display to aluminium box and tighten with two screws

Power

❏ Connect power, typicaly 13,8V from transceiver

Configure output driver

We available two types of output drive

Open collector

Using for components with grounding outputs

Put in ULN2803A chip to U5 dil socket
Set two jumpers in P2 to LEFT side

Open emiter

Using for components controlled with positive voltage

Put in MIC2981 chip to U5 dil socket
Set two jumpers in P2 to RIGHT side
Connect power for output control to pin1 in J2 D-SUB connector| - this voltage use also for powered of band decoder and may be in range 8-24V

Configure outputs in firmware

Allways enabled.

An entrance band data, or frequency, converts to output band 0-14 which can be configured in the following table - Preset Band to output matrix - in default settings Band-1 corresponds to Output-1, etc. You can sets any combination outputs for each band separately. With change zeros and ones in the Matrix table. Band-0 reserved for out of range inputs measure.

 //=====[ Sets band -->  to output in MATRIX table

Configure TRX inputs

First sets global frequency rules which they choose BAND number by frequency with a resolution of one Hz. Also may be use for partition one band to more subbands.

//Freq Hz from       to   Band number
     {1810000,   2000000},  // #1 [160m]
     {3500000,   3800000},  // #2  [80m]
     {7000000,   7200000},  // #3  [40m]
    {10100000,  10150000},  // #4  [30m]
    {14000000,  14350000},  // #5  [20m]
    {18068000,  18168000},  // #6  [17m]
    {21000000,  21450000},  // #7  [15m]
    {24890000,  24990000},  // #8  [12m]
    {28000000,  29700000},  // #9  [10m]
    {50000000,  52000000},  // #10  [6m]
   {144000000, 146000000},  // #11  [2m]
   {430000000, 440000000},  // #12  [70cm]
   {1240000000, 1300000000},  // #13  [23cm]
   {2300000000, 2450000000},  // #14  [13cm]
   {3300000000, 3500000000},  // #15  [9cm]
   {5650000000, 5850000000},  // #16  [6cm]

Second uncomment and activate only one input in source code

Not need any hardware settings, only send via USB to serial line ascii characters in preconfigured baudrate.

X,YYYYYYY\n

X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.
\n - is LF Line Feed (0A in hex)
